About this 4.5ct lab-grown cushion diamond

This 4.5ct lab-grown cushion sits in the three to five carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG838648263 or 838648263. Listed at 13 retailers as of October 31, 2026, with prices from €1,020 to €3,688, a €2,667 spread on the same certified stone. Taylor and Hart lists it at €3,688. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
